Product Description:

1.Description of Gasket :
Ginseal Spiral-wound gaskets comprise a mix of metallic and filler ma- terial. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flex- ible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support. These gaskets have proven to be reliable in most applications, and allow lower clamping forces than solid gaskets, albeit with a higher cost.
This gasket is formed with stainless steel 304/316 and graphite,non asbestos,ptfe or other seal material. It is the best gasket for muffler pipe or flang gasket.
It could be standard style,it just formed stainless steel and graphite or non asbestos etc.
It could be add inner ring or outter ring.The material ring  could be carbon steel or stainless steel.

2.Features of Gasket :
• Wide range of applicable working condition,high temperature and high pressure resistance,applicable to super low temperature and vacuum condition.Chemical resistant gasket is available under various medium,through change of composition of gasket.
• Strong stress compensation,stable and reliable sealing performance even under frequent pressure fluctuation condition.
• Perfect sealing performance.
• Normal requirement of flange surface finishing which contact with gasket.
• Easy installation and low pre-tightening stress of gasket.
• Heat treatment industry for furnace parts, fans, tube hangers, and baskets and trays to hold small parts.
• Chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide.
•  Food processing industry.
• Hot acetic and citric etc.
1.A.Wound style gasket consists of four type:basic type,with inner ring,with outer ring,and with inner and outer rings. B.Heat exchanger wound style gasket:basic type and with inner and outer rings.
2. Normally matrial used:
A.Steel tape:08F,0Cr18Ni9(304),0Cr18Ni9Ti,1Cr18Ni9Ti(321),0Cr17Ni12,M02(316),00Cr17Ni14M02(316L).

4.Specifications of the Gasket:
1.A good compression ratio and elasticity.
2.With plastic appropriate, after pressing can adapt to the sealing surface and sealing surface uneven fill the gap, to ensure good sealing performance with the temperature and pressure in the system of alternating case.
3.With excellent corrosion resistance, not to be damaged in some extreme medium, does not have the expansion and contraction.
4.Under the condition of high temperature softening, does not creep; under the condition of low temperature hardening, does not shrink.
5.Have sufficient strength, when external load conditions, not be crushed; at high temperature, not blown out.
5.FAQ
Ask 1: Why some supplier give me the price much cheaper than you?
Answer:They wanna attract your attention,while you contact with them,they would raise the price by any reason.

Q:Rubber products on tiles, why tiles yellow?
Rubber is a mixture of substances that can precipitate and cause yellowing. The term "rubber" is called frost"
Q:Properties and specific uses of various rubbers
Natural rubber is mainly derived from the Hevea tree. When the epidermis of this rubber tree is cut open, it will shed milky juice. It is called latex, and the latex will be natural rubber when it is condensed, washed, molded and dried.
Q:How long is the warranty period for EPDM?
Rubber product (rubber products) refers to the natural and synthetic rubber as raw material to produce all kinds of rubber products activities, including the use of waste rubber reproduction of rubber products.
Q:Several aspects of rubber aging performance and how to identify them
Rubber and rubber products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the physical and chemical properties and mechanical properties of rubber gradually deteriorated, and finally lose value, this kind of change is called aging of rubber
Q:What is the harm of rubber to the human body?
Depends on what rubber, and see what the rubber does. Some rubber additives used more, the processing of the flavor is more heavy, more toxic. If you do containers, try not to use it to store people's food, so as not to volatilize, causing harmful substances volatilization.Guidance opinion:Some of the rubber itself is no poison, and basically additive little, there will be no toxicity. Such as silicone rubber, but also can do food grade, used in tableware, artificial organs and so on.Rubber has a component called aniline, which contains a special odor.Harm: 1, blood damage, 2, liver damage, 3, urinary system damage, 4, nervous system damage, 5, skin damage and sensitization, skin itching, 6, crystal damage, 7 carcinogenic, teratogenic.Measures: keep the air circulation in the work place; the adsorption of poisonous gas; do personal protection; strengthen the monitoring of toxic and harmful substances in the workplaces; strengthen the occupational examination.May wear the gas mask, has certain function.
Q:How can rubber be preserved without decay?
Early rubber was made from latex of rubber trees, rubber grass and other materials made of flexible, insulating, impermeable and air. High elastic polymer compound. It is divided into two kinds: natural rubber and synthetic rubber. Natural rubber is made from rubber, tree, rubber, grass and other plants. The synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life.
Q:What are the common rubber products, please tell me
Rubber products mainly include tires, sidewall, rubber strips and inner tubes, as well as parts of automobiles. They are made of wires, cables, wrapping and high voltage and extra high voltage insulating materials. They can also make rubber shoes and guardOther light colored products, such as raw materials, and other general industrial rubber products, cushioning materials, conveyor belts and belts, oil resistant hoses, gaskets, and chemical resistanceCorrosion equipment lining.
Q:What about rubber molding, foaming and layering?
Return the glue (the rubber has not been used up after heat treatmentThe glue and the new rubber are mixed together to heat up, and the remaining glue is called a return glue. When the mixture is mixed with the new rubber, the mixture is uneven and the degree of vulcanization is not uniform, resulting in delamination
Q:What are the causes of the rubber products breach?
It's aging of rubberAging refers to the polymer materials (including rubber, plastics, fiber and so on) in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors, its performance gradually deteriorated, resulting in the final loss of use value.
Q:How can rubber and mould not be bonded when producing rubber products?
When rubber products are made, rubber and mould can not be bonded:1, abrasives to be polished, coating treatment, to achieve the most smooth surface and high temperature corrosion resistance requirements!2, formula design, less use of sticky, easy to corrosive materials;3, curing process should meet the requirements of formula design!
